Select tag not defaulting to Models value

I know this is a basic problem with a very simple solution but I''m new
to ruby and rails so I''m a bit confused why this isn''t working

I want to be able to create a select tag which is linked with a
particular model, so I used this code in the view

<%= start_form_tag :action => ''index''%>

    <%= text_field("user", "user_name")%>
    <%options = [["","0"],
["Low","1"],["High","2"]]%>
    <%=select("user", "level", options)%>

    <%= submit_tag ''test''%>

<%= end_form_tag %>

here''s the controller code

class TestController < ApplicationController

  def index
    @user = User.find_by_id(params[:id])
  end

end

I tested the above code using a user record with the field level
containing 2 and the select list did not default to 2 but stayed at
the empty option

As I said before, I''m sure I''m missing something obvious here
but I
haven''t a clue what, any ideas?

Cheers

Teesea

Re: Select tag not defaulting to Models value

Add The following to the top of the file.
<HR><PRE><%=params[:user].inspect -%></pre><HR>
Check to see what level is set to.

Frefesh the page to see changes to a form can be problimatic as well, as 
the browser will often remember what it was set to. (this drives me nuts 
when dealing with default values)

Re: Select tag not defaulting to Models value

Thanks for the tip, turns out the problem was that the field was of
type int but the option values i was giving rails were strings, I
didnt realise that it checked type when doing that, doh!

Re: Select tag not defaulting to Models value

I just ran in to the same problem, I added the "to_s" to the end of
c.id and that fixed the problem

<p><label
for="question_category">Category</label><br/>
<%= select("question", "category_id", Category.find(:all,
:order =>
"description").collect {|c| [ c.description, c.id.to_s ] }) %>

I''m surprised rails doesn''t handle this for you when creating
the
select.
